====== Meme-gene Co-evolution ======

====== Outline ======

{{INLINETOC}}

====== Introduction ======

===== Definition of meme =====

  - what are memes? replicators, horizontal transfer

===== Coevolution as a game =====

  - could have an interaction between memes and genes.  A meme could affect genetic fitness and vice versa
  - can frame in terms of 2-player game occurring in/at each individual
  - some cases (lactase) are cooperative (coordination/staghunt)
  - but could exist some competitive scenarios (eg. chicken).  Example?

===== The big question =====

  - unclear what to expect.  Can memes "get off the leash"? (Blackmore 2000)  Can they have a deleterious effect on genetic evolution?

====== Results ======

  - 14 games have single NE.  Expect simulations to converge to NE
  - 2 games have multiple NE: staghunt & chicken
  - staghunt: coordination problem.  Can beneficial meme/gene pair invade?
  - chicken: can memes get off the leash?  Can memes drive genes?  Under what conditions?

====== Discussion ======

  - review: what we did and what we learned
  - idea: different population structures
  - idea: what about PD?  What would sustained cooperation even mean in this case?  A: Memes and genes select C to mutual benefit despite incentive for D.
